Use the arrow keys to move. Click the tiles to change them. Press 0-4 while clicking to go to a different tileset. The amazing art is all done by @maximiliaan. It looks incredible! (It also looks best in fullscreen) If you want to restart the whole map, go inside and run the "create map" script once. Decorations are to not be seriously overused, as the clone limit is 300. (That leaves you 108 decorations to mess around with on screen...)
